The problem with letting your son borrow the digital camera is that sometimes he messes with the settings and if you're not paying attention the only two pictures you take of his first day of school turn out crappy. The other problem is, you'll end up with a bunch of pictures of your butt.
As for Max's reaction to Kindergarten, he wasn't overly excited or scared...just accepting. I tried to get him to care when I left but he didn't. The only emotional person in the group was Sam who refused to leave the building and kept insisting--at the top of his lungs--that "I FIVE NOT FWEE!!!"
